山麓-12度降雪15cmふきだまり発達、モイワ850m-14度西15m/s雪庇ふきだまり発達中、アンヌプリ1150m-24度西北西30m/s雪庇発達ふきだまり150cm、ヒラフ1250m-19度雪庇ふきだまり発達、日本海神威岬西南西19m/s気圧997hPa波高3.1m、

 

気圧の傾き強く山麓も吹雪、ふきだまりの発達は急激で標高800m付近の雪庇は大きく成長。1月9日層上のふきだまりは東側に80cmで発達中。全体の雪崩リスクは非常に高い。標高800m以上のゲートは閉じられる。周辺の山も雪崩が起こりやすい。今日は山に行かないほうが良い。午後に風が落ちても雪崩の危険は続く。

 

この情報は事故防止のために出されている。雪崩は自然現象でありそこに人がいれば事故が起きる。過信せず危険を軽視せず慎重な行動を。山はそのうちに良くなる。事故が起きないことを願っている。寒いので凍傷に注意。

 

Niseko base: -12℃, 15cm snowfall and snowdrift development. Moiwa850m: -14℃, W15m/s, cornices and snowdrifts developing. Annupuri1150m: -24, WNW30m/s, large cornices and snowdrifts (up to 150cm) developing. Hirafu1250m: -19℃, cornices and snowdrifts developing. Kamui cape lighthouse: WSW19m/s, 997hPa, 3.1m waves.

 

The tight isobars have brought the storm. Snowdrifts are developing drastically and cornices around 800m elevation have grown big rapidly. The newly formed wind-drifts on top of Jan 9th layer have reached up to 80cm and growing in east-facing slopes. The overall avalanche risk is extreme today. All gates above 800m will be closed. Similar hazard level applies to surrounding mountains. Today is not the right day for touring. The hazard level will stay high for a while after the wind calms down in the afternoon.

 

This information is issued in hopes to prevent accidents. Avalanches are natural occurrences and only become an accident only if a person is involved in it. Never underestimate the risk you’re taking. Being prudent and making conservative decisions are key to avoid accidents. The conditions will turn better soon. We strongly hope there will be no accidents during this storm. It’s cold out there, beware of frostbites.
